to the top of the guides l l' so that it Will clear the line ofdeposited cakes upon the holder C. An antifriction-rcll g is preferablyarranged at the opposite ends of the bar G to 5 travel upon the frame Aand guides l I',

thereby reducing friction.

Beneath the holder C "s a tank or receptacle di, containing the icingfluid, and the arrangement is such that when the holder C -xo is given ahalf-revolution the cakes or articles thereon will be suspended in iverse position directly above the icing luid. To coat the articles, thelevel of the fluid must be raised, and this l preferably accomplish bydisplacer ment. As shown, Lis a chamber at the bottom of the tank K, inwhich a piston M is litted, this chamber and piston preferably ex-`tending the full width of the tank.

h' is a partition separating the chamber L' level of the lluid in theupper portion o the receptacle K until the upper edge of the flange j'is reached. Any lui-ther displace ment of the fluid by the piston M willcause an over-How over the. llangc j without further raising the leveldi the iluid. Thus the height to which the iluid is -raised is exactlypredetermined and is such that the articles on the holder C'will becoated without depositing any of the icin;r material upon the holderitself. ln the return movement of the piston M the fluid is again drawndown intothe 1 chamber L or is sufficiently depressed to provideclearance for the holder during its rotary movement.

. The surplus icing-material adhering to the articles alter the' coatingoperation is re moved by a scraper. This preferably comprises ascraping-blade N, which extends transversely of the machine and iscarried by.

a rock-frame 0, iivorally secured at P preferably to the tan K. rollcarried by a rock-lever' ll, also pivoted at P, said .roll being adaptedto fbe engaged with a flange S at the end of each suction head C 0; T isan adjustable link .connecting the lever .it with the rock-frame Theobjectpof this const on to maintain the scraper-blade N ed distance fromthe p'late c of the suctrornhcad during the rotation of the latter, andthis distance may be adjusted by means of the link T. .Thus the blade Nmay be set so as to scrape oli the Is-irplus icing material, leaving acoating upon 5 5 the articles of uniform thicknees.V The ma Q is anantiffriction` sienes terial removed bythe blade N Will drop olitherefrom into an extension K' of the receptacle K and will be returnedto theY body of icinfr fluid.

vT ie various parts of the apparatus thus 7c far described are operatedfrom a' common drive mechanism in properly-timed relation, preferablythrough mechanism of the following construction: `U is a drivepulley ona shaft U', ,iournaled in the frame, and U2 U3 75 are intermeshihg gearsrespectively on said shaft U and a parallel shaft V. Upon the shaft V ismounted a cam V', which operates a rock-arm V2, connected by a link V3with a lever "J4, said lever being connected to a rod V5 foractuatin theplston M. U on the same shaft V is a so mounted a cam Vl which actuatesa rock-arm YV', .link W2, and lever- VW, the latter heilig connected byalink W4 with the pusher E. The pusher Gis also actuated by thismechanism through the mediurn of pivotal. links G', which extend' uponopposite sides of the frame 'and are' .pivot-alli'v attached at Gz tothe pusher E. 'lhe shaltr V has also attached thereto a crank X, which'9o is pivoted to a bearingblcck X', slidably enf `gaging a slottedrock-arm X2, pivoted at X".

T is a link connecting the block X' with a rock-arm i pivoted upon ashaft Ya and 1ntermittently rotating said shaft through the medium of apawl V3 on the roclcarm engaging a ratchet or notched Wheel Y* on theshaft. YS and Y6' are intermeshing gears res )actively on the shaft Yand rotary holder C, by which the latter is iven an interniittent rotarymovement. l is a feed-belt onto which the coated articles are deliveredfrom the holder C, said belt being intermity tcntly actuated by asuitable iced medianism which l deem it unnecessary to describe indetail.`

in the operation ci the machine the cakes or other articles to be coatedare placed by the attendantin the several tubular holders a ol the rece)taule E, the lower cake resting upon the ta le F. I Motion beingimparted to 'the various parts of the machine through the mechanismdescribed, the iirst movement in the coating operation will be thetransfer of a series of cakes from the bottom' of therecepf-x u; tacleBto the holder C5, this being edecte'd ulrthe forward movement of thepusher'J. When the cakes are thus deposited upon tha plate r of one ofthe suction-hcadaC,-Ci, tion will be conununicated throughfthe'crank izoX, sliding bearing X', rod lY, rockarm Y', paw Y, and ratchet-wheel toshaft '2 and from the latter, throu h the inter-.- meshing gears Yandfi-to the older C,the amount of movement being just sufficient to turnsaid holder through a one-bali` revolution, thereby reversing ,thepositions of the suction-heads. During' the initial Inovement of theholder C the slot e; communicating with the chamber in the uppesuctionfx3c tion means voperating to level in the cor'itainer, for the .purposede scribed. i

12. In a coating-machine, the combination with a containerfor thecoating duid, of a holder vfor the articles to be coated arranged to-bemoved from a loading position to a position in operative relation tosaid container and thence to an unloadosition, a sucllirdi the articleson said holder, and means for raising the surface of the iuid intocontact with the articles when said holder is in the coating position.

13. In a coatin -1nachine,the combination With a container or thecoating Huid, of a reversible holder for the articles to be coated,means for Acausing the surface of the fluid tov contact with thearticles When said holder is in its reversed osition, an adjustablescraper' for removing t 1e surplus iuid from the article, and a guidefor the scraper, substantially as described.

14. Inacoatin -machin'efthe combination with a holder an means for'feeding" articles onto said holder, of a across said holder, an

described.

l5. In a coating-machine, the combination With a holder for thearticles, of a pusher, means for reciprocating said. pusher across saidholder, and means compelling said pusher to take different paths in itsadvance and return movements, for the purpose described.

In testimony whereof I aflix my signature in presence of two Witnesses.
